If there is any other place in the world that hides the beauty and splendor of nature like the depths of the ocean, then it would be caves. These crevices and cavities created under the earth or within mountains have a good amount of majesty to share with explorers and adventurers. Breathtaking, intricate, and massive,this is the best amazing cave with me : Cave of the Swallows – Aquismon, Mexico

An open airpit cave situated at the Municipality of Aquismon in Mexico, it has freefall drop of 333 m from the floor of the cave to the lowest side of the opening, with 370 m drop from the highest side. The 2nd deepest pit in Mexico and the 11th in the world, a skyscraper like the NYC Chrysler Building could easily fit. The cave has low temperatures with thick vegetation at the mouth and rains can cause waterfalls to cascade into its opening. Aside from the layers of debris and guano, you can also find a sinkhole in a fault of the lower Cretaceous limestone, which can go down further to 512 m.
